Quick Question Coil issue or more? (Mopar but not A-body)

What’s the voltage to the coil? Blue wire. Could be a coil. They can do strange things like quit all at once, go intermittent, and get weak.

if You have spark and timing hadn’t changed and it’s not running next in line is fuel.
I'll check voltage at the coil tonight. Fuel, line, pump and filter and carb are good that was the first thing I checked before pulling a plug and not getting any spark.
